GOGGLES.

Specification of Letters Patent.

Application filed October 25, 1915. Serial No. 57,673.

To all whom it may concern Be it known that I, FRANK E. WEEKS, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Goggles, of which'the following is declared to be a full, clear, and exact description.

This invention relates to goggles of that class constructed of thin, flexible, transparent material, such as celluloid, and its principal object is to produce goggles of this class without the necessity of cutting notches in the end portions, or folding and lapping the end portions to produce thev bulging effect necessary in goggles of this class.

Another object is to provide goggles, with ventilating ducts, which goggles may be constructed of a single piece of material, having a peculiar outline, whereby the ventilating ducts may be produced as a result of the method of forming up the bulging portions. I

The invention consists, therefore, in a pair of goggles made of a single piece of thin, flexible, transparent material, bent or formed up at the end portions to give the bulging effect, part of the material being employed to form the ventilating ducts or conduits for the escape of moisture which might otherwise collect on the inner face of the goggles. The invention further consists in the several novel features hereinafter described and claimed.

- The invention is clearly illustrated in the accompanying drawing in which:

Figure 1, is a plan of a pair of goggles embodying a simple form of the present invention, partly broken away; Fig. 2-, is a front view thereof; Fig. 3, is a face view of a fragment of a blank from which the body of the goggles is made; Fig. 4, is an end elevation of the goggles, the binder for the edge being omitted from the view; Fig. 5, is an edge View of a fragment of the body, and ventilating duct looking toward the right in Fig. 4:, and Fig. 6, is a perspective view of a dust guard used in the ventilating duct.

Referring to said drawing the reference numeral, 10, designates the thin flexible, transparent body portion of a pair of goggles embodying a simple form of the present invention; said body portion may comprise celluloid or other thin flexible, transparent material, which, if desired, may

be colored or tinted to partially obscure brlght light rays. goggles is preferably arched slightly and the ends 11, are rounded as usual; the lower edge has an upwardly extending notch, 12, whereby the goggles may fit over the nose. In cross section the transparent body portion is curved or bowed outwardly somewhat, partlcularly at points in front of the eyes of the wearer and the extreme end portions extend backward, so as to contact with the face of the wearer. To the edge of the body portion is secured a binder, 13, which may be fastened thereto in any suitable manner; for instance if a rubber binder is used, it may be secured thereto by an adhesive substance, and if tape or other cloth binder is used, it may be stitched thereto at the edge. 7

At the ends 11, of the goggles are vents or ventilating ducts, 15, which may be formed by bending the material outward into the shape of hollow cones, 15, which open into the hollow or concave side of the goggles, through slots, 16. In the hollow of each cone, 15, may be secured a piece of gauze, 17, which covers the slot, 16, and prevents dust and dirt from entering the concave side of the goggles through the vents or ventilating ducts, and said piece of gauze may be in the form of a cone fitting against the inner face of the cone, 15.

In forming the present invention, the celluloid sheet or other thin flexible, transparent material is first cut into a blank 18, the end portions of which have the outline seen in Fig. 3. Each end portion 19, of said blank between the angularly disposed dotted lines a, 0;, (shown in Fig. 3) is then bent or folded outward around a tapered, heated mandrel (not shown) thereby forming up the cone shaped ventilating ducts 15, and at the same time drawing together the upper and lower end portions 20, 21, of the blank, and producing the bulging portions, which are intended to occupy portions in front of and at the sides of the eyes of the wearer. The length of the lines a, a, and the angle between them are so proportioned with respect to the remainder of the body portion as to produce a small cone shaped ventilating duct and to give the proper bulging effect'to the goggles over the eye. In forming the cone shaped ventilating ducts, the material is not brought close together at the point of juncture between said cones and main The upper edge of the Patented Oct. 1'7, 1916.

body portion, but the triangular shaped slots 16, are left between them to afford air pa ssages between the cones and the hollow or concave sides of the goggles. After the ventilating ducts have been formed, the gauze cones 17, may be inserted therein, and the binding 13,.secured to the edges of the main body portion, said binding spanning the gaps between the edge of the cones andmain body portion, thereby maintaining the parts in the shape resulting from the formation of the cones on the body. An elastic band (not shown) or other attaching means is secured to the end portions of the goggles in the usual and customary manner, for securing them upon the face of the user.

While I have shown and described the main body portion and cone shaped ventilating ducts as formed of a single sheet of material, it will be readily understood that the ducts may be made of separate pieces of material secured to the main body portion, furthermore that other variations and alterations of the device are possible without departing from the spirit of this invention; I desire therefore, not to limit myself to the exact form shown and described, but intend in the following claims to point out all of the invention disclosed herein.

I claim as new and desire to secure by Letters Patent.

1. As a new article of manufacture, a pair of goggles, comprising a piece of thin, flexible, transparent material, having bulging end portions formed by shaping the ends of said material into cone shaped portions, lying exterior of the bulging portions.

2. As a new article of manufacture a pair of goggles having bulging end portions, formed with externally located ventilating ducts opening to the hollow side of the oggles, and gauze pieces covering the openings between said ventilating ducts and hollow side.

. 3. As a new article of manufacture a pair of goggles, comprising a piece of thin, flexible, transparent material having bulging end portions formed by shaping up the end parts thereof into cone shaped portions, the hollows of which open into the hollow sides of the bulging portions.

4. As a new article of manufacture a pair of goggles, comprising a piece of thin, flexible, transparent material having bulging end portions formed by shaping up the end parts thereof into cone shaped portions, the hollows of which open into the hollow sides of the bulging portions, and a binder secured to its edge and spanning the gaps between the cones and body of the goggles.

5. As a new article of manufacture a pair of goggles, comprising a piece of thin, flexible, transparent material having bulging end portions formed by shaping up the end parts thereof into cone shaped portions, the hollows of which open into the hollow sides of the bulging portions, and removable cone shaped gauze pieces secured in said cone shaped portions.
